An atoll changes into a guyot primarily due to geological processes involving volcanic activity and erosion. Initially, an atoll forms around a volcanic island as coral reefs develop, but as the volcanic island erodes and sinks due to tectonic activity, the coral continues to grow upward. Over time, if the island submerges completely, the remaining coral structure becomes a flat-topped underwater mountain, known as a guyot. This transformation reflects the dynamic interplay between coral growth and geological changes in the Earth's crust.
